SCCS Number: SCCS/1687/25
Adopted on: 17 December 2025

Conclusion of the opinion:

1. In light of the new data provided, the previous SCCS Opinion (SCCS/1665/24) and taking under consideration the classification as toxic for reproduction Cat. 2, does the SCCS consider micron-sized particulate Silver [100 nm < particle diameter < 1 mm] safe when used up to a maximum concentration of 0.2 % in rinse-off and 0.3 % in leave-on cosmetic products?

In the light of the new data provided, indicating that micron-sized particulate Silver does not penetrate the skin, the SCCS considers micron-sized particulate Silver [100nm<particle diameter<1 mm] safe when used up to a maximum concentration of 0.2% in rinse-off and 0.3% in leave-on cosmetic products, as specified in the Tables 5 and 6.

This Opinion does not apply to the use of micron-sized particulate Silver [100nm<particle diameter<1 mm] in propellant-based spray products because such applications were not covered by the Applicant, and therefore not assessed for safety by the SCCS.

2. Alternatively, what is according to the SCCS, the maximum concentration considered safe for use of micron-sized particulate Silver [100 nm < particle diameter < 1 mm] in cosmetic products?

/

3. Does the SCCS have any further scientific concerns with regard to the use of micron-sized particulate Silver [100 nm < particle diameter < 1 mm] in cosmetic products?
